I'm a bit confused.
Did you (A) run the diesel with a pressurized air feed, or (B) run the diesel while the entire engine is under pressure? If you're under 33 feet of water in an ambient sub, the air pressure is doubled. 66 feet, and it's quadrupled. My question is: If the engine is used to a certain air/fuel ratio at the surface, and you start the same engine where the air is now four times a dense, does it care? Will it run?
Mind you, I'm not interrested in running an ambient sub under 66 feet of water with a deisel, and I can only begin to imagine how dangerous it would be to use a running deisel engine to head to the surface! My question is purely academic... not practical.

Yes the Diesel will run as long as you have O2 at the intake, I have studied feeding the engine from an pressurizes air flask but when you do the math the volume of air needed is alot in testing I found a 50 cc Honda engine would run out of air in about 1 min.using a 5 gal. tank at 100 PSI. pressure is the answer, and we all know high pressure is expensive and can be dangerousWT
